Connector Module Door Structure Push Rod Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The thinning of portable electronic device casings makes it difficult to load and unload electronic cards, such as memory cards, due to their smaller thickness compared to the width of a finger.
Innovation Solution
A connector module with a door structure and push rod mechanism that allows for easy ejection of electronic cards, where the push rod is hard and unbendable, and the door structure includes a connection rod for secure engagement with the connector, enabling the push rod to press the card effectively for ejection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the casing of portable electronic devices is made thinner to reduce overall thickness, then the device becomes more compact and portable, but the loading and unloading of electronic cards becomes more difficult
Solution Approach 1:
A push rod is introduced as an intermediary mechanical element between the user's manual input and the electronic card. The push rod amplifies the pressing force applied by the user, enabling effective card ejection despite the reduced thickness of the device casing that would otherwise prevent sufficient manual pressure application.
Solution Approach 2:
The invention changes the mechanical parameters of the ejection system by using a rigid, unbendable push rod with specific dimensional characteristics. The push rod's length, diameter, and material properties are optimized to provide sufficient leverage and force transmission within the constrained thickness of the thin device casing.
2Ease of operation
If a push rod mechanism is added to enable easy card ejection, then card unloading becomes easier, but the device structure becomes more complex
Solution Approach 1:
The push rod mechanism is merged with the existing door structure of the connector module. The push rod is integrated into the door assembly, sharing common mounting points and structural elements, thereby reducing the overall complexity that would result from adding a completely separate ejection mechanism.
Solution Approach 2:
The door structure serves multiple functions: it provides access to the card slot, houses the push rod mechanism, and acts as a structural support element. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in device complexity while achieving easy card unloading.

AI summary
A connector module and an electronic device using the same are provided. The connector module is disposed on a main body of an electronic device, and comprises a connector and a door structure. The connector has a slot used for accommodating the electronic card. The door structure comprises a door, a push rod and a connection rod. The door is used for covering the slot. The push rod is connected to the door and used for pressing the electronic card. The connection rod is disposed on the door and movably connected to the connector. When the door structure covers the slot, the push rod enters the slot and staggers with the electronic card.
